VALVE.

SPECIFICATION forming part of Letters Patent No. 671,971, dated April 16, 1901.

Application filed J' une 5, 1900. Serial No. 19,167. (No model.)

To all whom iv' may concern,.-

Beit known that I, HENRY LIPPOLD, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to valves; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims.

The object of the invention is to form a valve in which the seats of the primary valve may be repaired or renewed, while the valve as a whole is subjected to pressure to form an improved seat, aswell as other features of construction, which will be fully described, and pointed out in the claims.

The invention is illustrated in the accompanying drawings, as follows:

Figure l shows a vertical section through the center of the valve. Fig. 2 shows a plan view of the valve, parts being removed to better show construction. Fig. 3 shows a section similar to Fig. l of part of the valve. Fig. 4. shows a view of the nut for operating the primary valve, said nut being reduced from the size shown in Fig. l'. Fig. 5 shows a plan view of said nut.

opening a', forming the passage through the,

valve. Extending above the chamber is a projection A3, which is provided with an opening. This opening is provided with the 'internal screw-thread a2, into which is screwed the secondary valve B. This secondary valve B is provided with the external screw-thread b, extending throughout a considerable portion of its length to allow of its movement by being turned in the screw-thread a2. This valve is seated on the top of the diaphragm a. The valve is hollow and is of sufficienty Fig. 6 shows a section through the center of the primary-valve internal diameter to allow of its movement past the valve-disk E and the removable valve-seat F. On the top of this secondary valve B are the segmental notches b', into which fit the segmental projections c on the nut C. The nut C is provided with the screwthread, in which the thread d on' the stem D of the primary valve operates. The lower end of the stem D is provided with the flange d'. This flange is placed in the socket e in the valve-disk E; The socket e is screwthreaded, and the nut e is screwed into this socket, thus securing the valve-disk to the stem and at the same time allowing the stem to have rotative movement relatively to the disk. A nut B' is screwed into the top of the secondary valve B against the projection c on the end of the nut C, thus locking the nut C both axially and rotatively with the nut B. The nut C is provided with an extension C', which is finished, and at the outer end of this extension there is arranged a squared portion C', on which may be placed a wrench to turn the nut C, and consequently the valve B. The upper end of the nut O is providedwith the gland (l2 for forming a joint with the stem D. The projection A3 is provided with the external screw-thread d4. A cap-coupling G is screwed onto this screw-thread. The cap is provided with the seat g, which is adapted to form a seat with the top of the projection A3. The cap is also provided with a seat at the top g', which is adapted to form a-seat with the ring c2 on the nut G when the valve B is screwed to its extreme outer position. A handle D is provided for operating the primary valve E.

A removable seat-ring F is provided, and this is screwed into the opening 0,. It has the lug f', by which it may be turned out or screwed into place. The contact portion f or seat proper is V-shaped. The valve-disk is provided with a V-shaped groove e2, which engages the seat f.

The operation of the device is as follows: When it is desired to repair, remove, or renew the valve-disk E or the valve-seat f, a Wrench is placed upon the squared portion C and the valve B is screwed down against the diaphragm a. This shuts the valve proper off from the entrance-opening A. When the valve B has seated itself upon the diaphragm seat-ring c2 firmly against the seat g'.

A, it has also formed a seat through a packing b2 upon a seat a3in the projection A3. The packing b2 has suiieient elasticity to allow a perfect seating of the valve B2 upon the diaphragm A. The only purpose of the seat b2 is to prevent leakage through the threads at the outer edges of the valve. After the valve B is seated the cap G may be removed. This exposes the nut B', which may be removed, vand when this is done the nut C, stem D, and valve E may be withdrawn through the opening through the valve B. The valve E may then be repaired or renewed, and, if desired, the seat-ring F may then be removed through the opening in the valve B and a new seatring inserted in a similar manner. The parts may be assembled by reversing the above-described operation. After the parts are reassembled the valve E may be kept to its seat, as the valve B is removed by simultaneously turning the handle D and the nut C, or both valves may be opened together. The valve B is screwed out to a position that presses the This insures a closure between the nut O and cap G.

By making the seatf V-shaped and providing the disk with aV-shaped groove a perfect lit can be had with a metallic seat, as-anydirt or foreign substance lodging upon the Valve seat is crowded off as the parts are brought to position. Of course the groove and V- shaped portion may be reversed in relation to the disk and seat-ring, if desired, but Iprefer the construction shown.

What I claim as new is- 1. The combination of the valve-chamber; a primary valve and a secondary valve, one

` of said valves being hollow and of sufficient size to allow the removal or insertion of the other through it, said hollow valve being arranged to be moved to and from its closed position in an axial direction.

2. The combination of -a valve-chamber; a primary valve; and a seconda-ry valve, said secondary valve having an opening through it large enough to allow the insertion and removal of the primary valve through said opening, said secondary valve being arranged to be moved to and from its closed position in an axial direction.

3. The combination of a valve-chamber; a primary valve; and a secondary valve 0f annular shape and having an opening through its center large enough to allow the insertion and removal of the primary valve through it, said secondary valve being arranged to be moved to and from its closed position by a movement in an axial direction.
